Title: Improvements in or relating to cellular materials
Inventor: WOOD JOHN FRANCIS
IPC: C08G18/22
Filed: 1955-05-06
Abstract: The invention comprises cellular polymeric materials prepared by the interaction of polyesters and organic polyisocyanates characterised in that a substance containing ferrous iron is incorporated in the polyester/polyiso-cyanate reaction mixture from which the cellular material is prepared.  The substances containing ferrous iron may contain a minor part of the iron in the ferric state.  Specified are ferrous sulphate, chloride, bromide, iodide and nitrate, organic salts such as ferrous acetate and compounds containing other radicals such as ammonium, potassium and magnesium compounds, for example ferrous ammonium sulphate or chloride or ferrous magnesium chloride. Preferably 25 to 1000 parts per million parts (by weight) of polyester are used. Advantageously the polyesters employed are those described in Specification 790,420.  Mixing may be carried out in a continuous process, for example by the method described in Specification 839,183.  Suitable polyisocyanates are hexamethylene, toluylene, diphenylmethane: 4141, m and p-phenylene, monochlorophenyl-2:4- and dicyclohexyl-methane diisocyanates.  As catalysts there may be used triethylamine, N:N-dimethylcyclohexylamine, b -diethylaminoethyl benzoate, di-(b -diethylamino-ethyl) adipate, N:N-diethylbenzylamine, N-ethyl-hexamethyleneimine, N-ethylpiperidine and a -methylbenzyldimethylamine.  As emulsifying agents which may be added to the reaction mixture there can be used a fatty acid such as oleic or dodecanoic acid wholly or partially neutralised with an amine such as diethylamine.  Fillers, colouring matters or flameproofing agents may be added as dry powders or as premixed pastes with the polyester, the polyisocyanate or trieresyl phosphate.  In examples there is described the production of sponges by processes in which (1) a mixture of water, ferrous ammonium chloride, di-b -(diethylaminoethyl) adipate and diethylamine oleate is stirred into a mixture of toluene-2:4 and 2:6 diisocyanates and a liquid polyester from diethylene glycol, pentaerythritol and adipic acid; (2) a mixture (A) of water, ferrous sulphate diethylamine dodecanoate and b -diethylaminoethyl benzoate is blended continuously with a (B) liquid polyester from diethylene glycol, glycerol and adipic acid and (C) a blend of toluylene-2:4 and 2-6:diisocyanates; (3) a mixture (D) of water, ferrous ammonium sulphate, oleic acid, diethylamine and di-(b -diethylaminoethyl) adipate is continuously blended with (E) a mixture of toluylene-2:4 and 2:6 diisocyanates and (F) the liquid polyester of Example 1. Specifications 553,733, 579,340, 769,681 also are referred to.

Title: Improvements in or relating to time element electric relays
IPC: H01H71/44
Filed: 1938-05-03
Abstract: 515,473. Induction relays. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., CANDLER, J. E., and COLLEY, E. R. May 3, 1938, No. 13179. [Class 38 (v)] When coils 6 of a relay of the alternating current vane type are energised, the vane moves through part of its stroke but is prevented from moving its full distance till a synchronous motor, energised simultaneously with the coils, has slowly rotated a disc through a certain angle. In the form shown, the coils 6 repel a vane 2 mounted on an axle 4 causing the lowering of a link 10 and arm 11 and rocking of a member 14 so that contacts 12 are moved away from contacts 16. Before the member 14 has rocked sufficiently to cause contacts 13 to engage 17 the motion is stopped by an arm 18 on the axle 4 engaging beneath a disc 21, Fig. 4, and raising this bodily into engagement with a pinion 26 driven by the synchronous motor. The disc 21 now rotates clockwise, Fig. 4, and after a time interval a slot 32 in the disc comes opposite the end of the arm 18 allowing this to move upward and the switch contacts to complete their movement. At the same time the disc 21 drops out of engagement with the pinion 26. On de-energisation of the coils 6, the vane 2 moves back part way and the arm 18 moves out of the slot 32. Full movement is prevented by an arm 19 on the axle 4 engaging the periphery of another disc 22 mounted in front of the disc 21 and coupled to the disc 21 by an idler pinion 35. Gravity and a return spring rotate both these discs quickly to their original position and when this is reached the end of the arm 19 slips into a notch 33 in the disc 22, and switch members now complete their movement. The time delay occuring during the "operation" of the relay may be adjusted by varying the mutual position of the disc 21 which may for this purpose be temporarily declutched from the disc 22 which is locked by the arm 19.

Title: Improvements in and relating to mortars
IPC: F41A19/29
Filed: 1947-05-17
Abstract: 623,708. Bomb-throwers. ETABLISSEMENTS E. BRANDT. May 17, 1947, No. 13336. Convention date, July 1, 1946. [Class 92 (ii)] Relates to mortars or bomb-throwers of the kind in which the striker 9 is either locked in the projected position for automatic firing or is made movable, as shown, for controlled movement under the action of percussion mechanism. According to the invention the percussion mechanism is arranged in an independent case 7 housed in a rear extension of the breech. As shown, the case 7 is fitted with a knob 22 which when rotated causes the descent of a rod 25, the latter serving to rock a lever 26 having an arm 26b straddling a buffer knob 17 on a member 16. The knob 17 is thus forced towards the breechbody 2 first compressing a spring 19, which bears also against the striker 9, and then engaging a knob 9b of the striker so that the latter is moved to and locked in the position for automatic firing. The parts return to the position shown under spring action when the knob 22 is moved in the reverse direction, and an extension 25b of the rod 25 indicates how the mechanism is set. Controlled percussion is effected by rotating clockwise a hand lever on a shaft 34, such movement causing a lever 33 to act on a pusher 32, thus compressing a spring 31 which bears also on a hammer 29. On continued rotation of the shaft 34 a nose 41 on it engages with and lifts a sear 36, which was previously holding the hammer, thus releasing the hammer which then drives back the member 16 against the knob 9b of the striker to effect percussion. The parts return to the position shown by the action of the spring 31 when the firing lever is released, and may be locked in that position by a member 47 which engages in a notch 42 on a member secured to the shaft 34 when a control knob 49 is suitably rotated.

Title: Toy vehicle
Inventor: LINES WALTER MORAY
IPC: A63H17/00
Filed: 1969-07-13
Abstract: 1,261,931. Wind propelled toys; indoor games. LINES BROS. Ltd. 28 April, 1970 [13 July, 1969], No. 13356/69. Headings A6H and A6S. A wind-propelled toy vehicle, e.g. a yacht, has two wheels 3 and 4 mounted co-axially, but independently amidships, a third bow wheel 5 mounted about an axis parallel to the wheels 3 and 4, and a stern support peg 6 which can slide smoothly over the supporting surface 7. The vehicle may rock about the axis of wheels 3 and 4 so that either wheel 5 or peg 6 are in contact with ground, but not both, these positions being indicated by the full and broken lines respectively and in the figure. The yacht has a mast 8, with a mainsail 9, and jib-sail 10, a boom 11 extends along the lower edge of the mainsail 10, and carries a weight 12; the boom can pivot horizontally about the mast 8, 45‹ forward in either direction, but tends to adopt a position extending sternwards because of the nature of the pivot 13 which is shaped somewhat like a rising butt door hinge. The pivoting of boom 11 from its normal position to either forward position displaces the centre of gravity of the yacht from a position along line 14 to a position along line 15. This may be accomplished by directing a stream of air at the mainsail e.g. by means of an electric blower, and when the boom is in this forward position the yacht adopts the position as shown by the solid lines in the diagram, i.e. with wheel 5 in contact with the surface 7, and the yacht may be propelled along the surface by continuing to direct the airstream at the mainsail 9. If this air stream is discontinued then the boom 11 will tend to swing back to the astern position, thus displacing the C of G to the rearward position and causing the yacht to adopt the position indicated by the broken lines in the diaphragm, i.e. with peg 6 resting on surface 7, in this position the yacht may be turned by directing the airstream at jibsail 10, and thus enabling the yacht to be propelled on a new course by again directing the airstream at the mainsail 9. A game may be provided by means of at least one yacht as described at least one electric blower and a surface 7 having upon it a plurality obstacles to be negotiated.

Title: Quaternary ammonium compounds
Filed: 1956-05-04
Abstract: The invention comprises quaternary ammonium compounds formed from one mole. of tris-(dimethylaminomethyl) phenol and one to three moles. of a compound comprising a hydrocarbon group or a substituted hydrocarbon group having ten to twenty-one carbon atoms attached to a reactive halogen.  The compounds of the invention are prepared from tris-(dimethylaminomethyl) phenol and organic halides of formula RX, where R is C10-C21 hydrocarbon or substituted hydrocarbon and X is a halogen.  Many values are specified for R viz. alkyl, alkenyl, mono-, di-, or tri-alkylbenzyl, alkadienyl, alkynyl, alkenylbenzyl, alkynylbenzyl, alkoxyalkyl, or hydrocarbon groups substituted with ester, ketone or amide groups.  Any of the geometrical isomers or a mixture of isomers of the tris-(dimethylaminomethyl) phenol may be used.  When more than one mole. of RX is reacted with a mole. of tris-(dimethylaminomethyl) phenol, RX need not represent the same specific compound.  A catalyst, e.g. sodium iodide may be used in the reaction process, which preferably takes place at 50-150 DEG  C., preferably the reflux temperature of the reaction mixture at atmospheric pressure or above, a solvent such as ethanol, isopropanol, butanol, nitromethane, acetonitrile, dimethyl formamide, dioxane, propyl ether or butyl ether may also be present.  The reaction is continued until the required number of moles. of RX has reacted with the tris-(dimethylaminomethyl) phenol, as determined by estimating the theoretical amount of ionizable halide in the reaction system.  Examples are given of the preparation of compounds from one unit of tris-(dimethylaminomethyl) phenol, and 1, 2 and 3 units of dodecylmethylbenzyl chloride, three units of dodecenyl chloride, three units of decyl bromide, three units of propoxydecyl chloride, three units of bromododecanamide, three units of octylbenzyl chloride, one unit of dodecyl chloride, one unit each of dodecynyl chloride, decyl bromide and propoxydecyl chloride.
